1N989B - Silicon 500mW Zener Diodes

This page provides the datasheet information for the 1N989B, a member of the 1N957B Silicon 500mW Zener Diodes family.

Description

The popular 1N957B thru 1N992B series of 0.5 watt Zener Voltage Regulators provides a selection from 6.8 to 200 volts in standard 5% or 10% tolerances as well as tighter tolerances identified by different suffix letters on the part number.

Features

  • JEDEC registered 1N957B(-1) to 1N992B(-1) series.
  • Internal metallurgical bond option available by adding a “-1” suffix (similar to military product).
  • Surface Mount equivalents available as MLL957B to ML.
